Abstract

Summary

Airborne Electromagnetics (AEM) has been used to map the extent of environmentally harmful black shale in two geotechnical projects in Norway, supported by electrical resistivity ground surveys and laboratory measurements. The work demonstrates that resistivity is a suitable parameter for both mapping and characterizing black shales, since their high sulfide content in general means a more harmful shale and in addition gives very low resistivity (0.1–1 Ωm). Various interpretation procedures to define a black shale volume have been explored, and some of the data show vertical resolution sufficient for geotechnical applications.
